[native_assets_builder] Fail early on too old native_assets_cli

[dcharkes]

Since we know the PackageConfig, we can check in the native assets builder what version of native_assets_cli is used in the hook implementations.

Since we know the PackageConfig, we also know the package root of native_assets_cli and try to find the version of the protocol it's using.

If we find that the protocol version is no longer supported, give an error message early and stop building native assets instead of actually invoking the hook.
